Ad-hoc signing produces a new code signature on every build, and macOS records
privacy grants (Accessibility, Screen Recording, Microphone) against the
signature rather than the path. Every rebuild therefore looked like a new app
and silently lost its permissions — the symptom being VoiceInk asking for
Accessibility while System Settings showed it already enabled, with several
stale TCC records accumulated behind one visible row.
- Add scripts/make-local-signing-cert.sh to create a stable self-signed
code-signing identity, and repair the trust setting when a certificate
already exists but is not yet a valid identity.
- `make local` re-signs the built app with that identity when present. It is
done after xcodebuild rather than as a build setting because the app target
defines CODE_SIGN_IDENTITY[sdk=macosx*], which outranks both the xcconfig and
the command line — Xcode silently falls back to ad-hoc otherwise.
- Add com.apple.security.cs.disable-library-validation to the local
entitlements. A self-signed certificate carries no Team ID, so the hardened
runtime refuses to load the app's own dylibs ("different Team IDs") and the
app dies at launch. Release builds keep library validation enabled.
- Pass -skipPackagePluginValidation / -skipMacroValidation. The mlx-swift
dependency ships a CudaBuild plugin that Xcode blocks pending a one-time GUI
trust click, which no command-line build can satisfy — a clean `make local`
failed with Error 65 for anyone who had not already clicked it.
(cherry picked from commit a8609c5)
Foundation work behind the surface changes that follow. Design system - AppTheme gains Typography, Spacing, Motion and Recorder token groups. Typography is built on relative text styles, so the app responds to Dynamic Type; 537 hardcoded .font(.system(size:)) call sites previously prevented it. - AppCardBackground and AppMaterialCardBackground now use continuous corners. They were circular, which reads wrong next to native macOS controls, while MetricTintBackground in the same file already used continuous. - Split the mis-wired sidebar colour token: AppTheme.Sidebar.audio (pink) was applied to the History row while Audio fell through to fallback grey. Window - Remove the fixed 950pt width. minSize/maxSize both pinned it, the root view hard-set .frame(width:), and the scene used .windowResizability(.contentSize) — even though DashboardLayout already computes a width from the geometry. Now 820x560 minimum and freely resizable; a restored frame keeps its size rather than being snapped back to the default. - Wire Cmd-, through CommandGroup(replacing: .appSettings). The only binding previously lived inside the menu-bar extra's menu, so it fired only while that menu was open. Shell - Migrate ContentView from a hand-rolled HStack to NavigationSplitView, and AppSidebar to a List. This is what makes .searchable and .toolbar work at all in the detail views; without a navigation container they render nowhere. The coloured icon tiles are preserved, with selection, hover and keyboard navigation now inherited from the List. (cherry picked from commit 2b2d218)
History - Replace the Form-with-a-Section-per-row list with a List. Form does not virtualize, and every expanded row nested a ScrollView inside the outer scroll view, so a trackpad gesture over a transcript trapped the scroll. - Move selection from Set<Transcription> to Set<PersistentIdentifier>. Holding live SwiftData models in a Set retained deleted objects and relied on their identity staying stable. - Adopt .searchable with a 250ms debounce. Search previously re-ran a full predicate fetch on every keystroke. - Add keyboard support: arrows, Cmd-A, Delete, space to expand, Cmd-C, context menus. Replace the "Load More" button with infinite scroll, and the hand-built empty states with ContentUnavailableView. - Add transcript pinning and tags, with pinned items in their own section. Pinned is a separate section rather than a sort key because SortDescriptor requires a Comparable value and Bool is not one. Audio - Redraw the waveform as a single Canvas driven by TimelineView(.animation), replacing 200 individual bar views re-evaluated ten times a second from a published Timer. Playback completion now comes from AVAudioPlayerDelegate, which also removes a Timer being invalidated from deinit off the main thread. - Fix the waveform sampling: it stored abs(channelData[0]) — the first frame of each window — into an array named maxValues, producing a point sample rather than an envelope. It now takes the true peak across the window. - Add drag-to-select trimming with audio + transcript clip export. Recorder - Replace the flat opaque Color.black with a material, rim light and shadow, and move every literal Color.white to AppTheme.Recorder tokens. - Extract RecorderPresentation. Mini and Notch independently re-derived the same display state from the same inputs, and had already drifted. - Replace the Timer-driven dot animation with PhaseAnimator and the retained repeatForever spinner with TimelineView, and swap the DispatchWorkItem hover debounce for .task(id:). Also adds a Cmd-K command palette with fuzzy matching over destinations, modes and recent transcripts, and deduplicates two byte-identical dashboard callout cards into DashboardCalloutCard. (cherry picked from commit f8de200)
Migrates all 41 ObservableObject types to @observable and turns on Swift 6 language mode. Zero @published, @StateObject, @ObservedObject or @EnvironmentObject remain. Combine couplings that needed redesign rather than translation - ModeFormWarmupStore subscribed to objectWillChange on three services. It now wraps its snapshot build in withObservationTracking via a new re-arming ObservationBridge helper, which is strictly narrower: it wakes only on the properties the snapshot actually reads. - AIService and AIEnhancementService called objectWillChange.send() because their state lives in the keychain and UserDefaults, where Observation cannot see it. Replaced with an explicit externalStateRevision counter that the derived accessors read. - UpdaterViewModel used assign(to: &$x), which only works with @published, and RecorderPanelShortcutManager consumed $isRecorderPanelVisible.values. Both rewritten against Observation. Latent bugs surfaced by strict concurrency - Eleven deinit bodies touched main-actor state from a nonisolated context. @observable turns stored properties into computed ones, so lifecycle handles are now explicitly nonisolated(unsafe) or @ObservationIgnored. - FluidAudioStreamingProvider held an NSLock across await boundaries in nine places; converted to scoped withLock. - WhisperModelManager's KVO progress callback captured mutable locals while firing on an arbitrary queue; moved into a lock-guarded LockedValue box. - Recorder passed a non-Sendable Notification into a Task; it now extracts the AudioDeviceID in the observer. - AudioCleanupManager's Timer captured a non-Sendable ModelContext; replaced with a structured main-actor task, so the context never crosses isolation. Where a framework type is genuinely thread-safe but unannotated — NSCache, NSXPCConnection, XPC reply blocks, UserDefaults — the escape hatch is used deliberately and commented rather than applied blanket. Also removes a dead `import Charts` (Swift Charts is unused; all plotting is hand-rolled) and a no-op DashboardAmbientBackground that rendered Color.clear. (cherry picked from commit 17631fa)
Marking AudioDeviceManager @mainactor during the Observation migration made its CoreAudio property listener inherit main-actor isolation. That listener is invoked by CoreAudio on its own dispatch queue, so the runtime asserted the isolation and trapped in _swift_task_checkIsolatedSwift on every device change — plugging or unplugging headphones crashed the app. Make setupDeviceChangeNotifications nonisolated so the C callback does not inherit isolation, and hop to the main actor explicitly inside it. Adds a nonisolated logger for the one error path that setup can hit. Audited the other C-callback sites: CoreAudioRecorder is @unchecked Sendable and ShortcutMonitor is unisolated, so neither has the same problem. (cherry picked from commit 2feccbd)
Three additions that landed on main while this migration was in flight are legal
under Swift 5 and rejected by strict concurrency:
* GitHubCLIStarService cached its resolved `gh` path in mutable statics. Two
concurrent callers would race on it, so the cache moved into an actor. The
path search itself still runs off the actor.
* LicenseKeychainAccessibilityMigration holds a UserDefaults, which is
thread-safe but cannot express that in the type system — the same gap
already bridged for KeychainService.
* LicenseViewModel's deinit cancels two Tasks, and deinit is nonisolated under
Swift 6. Marked nonisolated(unsafe): Task.cancel() is documented safe from
any thread, which makes this one of the few places that escape hatch is the
right answer rather than a shortcut.
None of this changes behaviour. It is the cost of turning the checking on, paid
once.

The CoreAudio listener registered here passes `self` via `Unmanaged.passUnretained(self).toOpaque()` and dereferences it in the callback with `takeUnretainedValue()`. However, `deinit` tries to unregister the listener using a *different* closure literal. CoreAudio matches listeners by exact function-pointer identity, so the removal is a silent no-op. The stale listener survives deallocation, and the next audio device change triggers a use-after-free when the callback dereferences the dangling `userData` pointer. To fix this, store the listener closure in a property (or use a stable top-level C function) so the *same* function pointer can be passed to both `AudioObjectAddPropertyListener` and `AudioObjectRemovePropertyListener`.</violation>

P1: Custom agent: **Backward compatibility**
The new "Select All" action only selects rows already loaded into `displayedTranscriptions`, which is paginated (`pageSize = 20`). Previously, `selectAllTranscriptions()` fetched every matching transcription from the store and selected them all, so bulk Export/Analyze/Delete worked across the entire filtered history. After this change, users with more than one page of results will silently operate on a truncated subset, breaking the existing bulk workflow. Consider restoring a cross-page fetch (or a store-side select-all mechanism) so the action continues to respect the active search/tag filter across all pages, not just the ones loaded into memory.</violation>

P2: Custom agent: **Backward compatibility**
When a user removes a tag that is also the active filter, the filtered list can show stale rows that no longer match the predicate. `removeTag` saves the model change but never triggers a reload of `displayedTranscriptions`, because it skips the `reloadToken += 1` that `togglePin` and `deleteSelectedTranscriptions` use to force `.task(id: reloadKey)` to re-fetch. Adding `reloadToken += 1` after `save()` ensures the page is re-evaluated against the current store state.</violation>

P1: Custom agent: **Backward compatibility**
The `@unchecked Sendable` conformance on `CloudTranscriptionService` is unsound: the added doc comment claims mutable state is "guarded by locks or confined to one task," but `modelContext` is a non-Sendable SwiftData `ModelContext` with no lock or actor protection, and `openAICompatibleService` is a non-Sendable `lazy var`. Since the comment explicitly says instances are "handed between the engine's isolation domains," concurrent `modelContext.fetch()` calls from different actors can crash or corrupt SwiftData state—a functional regression under strict concurrency. Either pass a `ModelContainer` and create local `ModelContext` instances, introduce an actor/lock to confine all SwiftData access, or remove the `@unchecked Sendable` if the service is only ever used from `@MainActor`.</violation>

P1: Custom agent: **Backward compatibility**
The `@unchecked Sendable` conformance added here is paired with a comment claiming internal mutable state is "guarded by locks or confined to one task," but the class contains no locks, actors, or other synchronization for its mutable `manager` and `eventsContinuation` properties. In practice, these properties are accessed from both the `@MainActor` (`connect`, `commit`, `disconnect`) and a detached task (`sendAudioChunk`) within `StreamingTranscriptionService`, and the `cancel()` path dispatches `disconnect` without awaiting the send loop, creating a concrete window for concurrent read/write races on `manager`. Since the `StreamingTranscriptionProvider` protocol requires `Sendable`, this `@unchecked` annotation suppresses Swift 6 strict-concurrency diagnostics for code that is not actually safe, masking a real data-race hazard rather than fixing it. Either move the mutable shared state into a `LockedValue` wrapper or an actor, or clearly document the exact caller-side guarantees that prevent concurrent access.</violation>

<violation number="1" location="VoiceInk/Services/TranscriptionAutoCleanupService.swift:5">
P1: Custom agent: **Backward compatibility**
Adding `@MainActor` to this class causes the internal cleanup `Task {}` blocks to inherit main-actor isolation, so `sweepOldTranscriptions` and `cleanupOrphanAudioFiles` now run synchronously on the main thread instead of a background executor. Both methods perform blocking SwiftData `fetch` calls and FileManager file-deletion loops that can freeze the UI during startup or after transcription completion. Since each method creates its own `backgroundContext` and only briefly needed `await MainActor.run { modelContext.container }`, they should be marked `nonisolated` so the heavy work stays off the main thread.</violation>
<violation number="2" location="VoiceInk/Services/TranscriptionAutoCleanupService.swift:5">
P1: Custom agent: **Backward compatibility**
The `@MainActor` annotation makes the compiler treat `handleTranscriptionCompleted` as main-actor-isolated, but NotificationCenter dispatches selector-based observers synchronously on the posting thread, bypassing Swift actor isolation. At least one `.transcriptionCompleted` posting site (e.g., `AudioFileTranscriptionService.swift`) appears to post from a non-main context before doing its own `await MainActor.run`. If the notification arrives off-main, the SwiftData mutations (`modelContext.delete`, `modelContext.save`) inside the callback execute off the main actor, silently violating the isolation contract and risking crashes or data races under strict concurrency. To fix this, dispatch the callback body back to the main actor explicitly—for example by wrapping the `@objc` method body in `Task { @MainActor [weak self] in ... }`, or by switching `startMonitoring` to a closure-based observer on `.main` queue instead of selector-based registration.</violation>

This `@unchecked Sendable` conformance lacks the explanatory comment the PR description requires for every escape hatch. More importantly, the mutable stored properties (`baseURL`, `selectedModel`, `availableModels`, `isConnected`, `isLoadingModels`) are written from `@MainActor` methods and read from the non-isolated `enhance()` method, so the type is not actually thread-safe. Marking it `@unchecked Sendable` suppresses Swift 6 strict-concurrency checks and permits cross-isolation usage that can data-race at runtime.

Concurrent calls can race on `whisperContext` and drive the same whisper C context (setLanguage/setPrompt/fullTranscribe/releaseResources) at the same time, causing a data race / crash.

`configure()` no longer guarantees a synchronous snapshot refresh when dependencies change. Previously, `dependenciesChanged` triggered both `installChangeObservers()` and `refreshSnapshot()`. Now it only reinstalls observers and defers the refresh to `ObservationBridge`, whose `init` schedules `apply()` asynchronously via `Task { @MainActor in ... }` (see `ObservationBridge.swift`). This leaves `snapshot` stale and `hasSnapshot == false` after `configure()` returns, which is a functional regression for any caller that relied on the synchronous guarantee. Consider explicitly calling `refreshSnapshot()` inside the `dependenciesChanged` branch, or after `installChangeObservers()`, to preserve the old behavior.</violation>

After the `@Observable` migration, click-seeking while paused no longer updates the displayed time label because `seek(to:)` no longer triggers `@Observable` invalidation. Previously `seek(to:)` assigned a `@Published` `currentTime`, giving immediate UI feedback; now `currentTime` is computed from `audioPlayer?.currentTime` and the `TimelineView` wrapping the label is paused, so the stale value persists until playback starts or another stored property changes.

The `security import ... -A` invocation combined with `security add-trusted-cert -r trustRoot -p codeSign` weakens local authentication controls: any application running as the user gains silent, unrestricted access to a trusted code-signing identity.

The CoreAudio listener registered here passes self via Unmanaged.passUnretained(self).toOpaque() and dereferences it in the callback with takeUnretainedValue(). However, deinit tries to unregister the listener using a different closure literal. CoreAudio matches listeners by exact function-pointer identity, so the removal is a silent no-op. The stale listener survives deallocation, and the next audio device change triggers a use-after-free when the callback dereferences the dangling userData pointer. To fix this, store the listener closure in a property (or use a stable top-level C function) so the same function pointer can be passed to both AudioObjectAddPropertyListener and AudioObjectRemovePropertyListener.

P1: Custom agent: Backward compatibility
The new "Select All" action only selects rows already loaded into displayedTranscriptions, which is paginated (pageSize = 20). Previously, selectAllTranscriptions() fetched every matching transcription from the store and selected them all, so bulk Export/Analyze/Delete worked across the entire filtered history. After this change, users with more than one page of results will silently operate on a truncated subset, breaking the existing bulk workflow. Consider restoring a cross-page fetch (or a store-side select-all mechanism) so the action continues to respect the active search/tag filter across all pages, not just the ones loaded into memory.

Migrate to Observation and enable Swift 6 strict concurrency
ObservableObject/@Published→@Observableacross 38 types, with strictconcurrency turned on and the resulting diagnostics fixed rather than silenced.
This is the first of three PRs. It is the foundation the other two build on, and
it is deliberately the least interesting to look at — no behaviour changes, no
new features. Splitting it out means the two that do change behaviour can be
reviewed on their merits.
Why bother
Two crashes in this repo were concurrency bugs of the kind strict checking makes
impossible to write:
AudioDeviceManagertrapped on every audio device change. A CoreAudioproperty listener fires on a HAL queue and reached into main-actor state.
Under Swift 6 that is a hard trap, not a race you get away with. Fixed by
making the listener
nonisolatedand hopping explicitly._postWindowNeedsUpdateConstraintswhen a window was released while aGraphHosttransaction was still queued.Observation also fixes a real performance problem that
ObservableObjectcannot:it tracks reads per view rather than per object, so a high-frequency property no
longer invalidates every view that merely holds a reference to its owner. The
recorder PR that follows measures this — it was 12.2% of one core.
What is in here
@Environment/@Bindablecall-site changes that follow from it.
NavigationSplitViewshell, which the migrationtouched anyway and which the later PRs assume.
underpins the migration commit; happy to lift it out if you would rather.
make localsigned ad-hoc, so everyrebuild looked like a new app to macOS and dropped its Accessibility grant.
There is now a one-time
make local-cert. Also adds-skipPackagePluginValidation, without which a cleanmake localfails onmlx-swift's CudaBuild plugin.
a mutable-static cache moved into an actor, a nonisolated
deinit, and aUserDefaultsthat is thread-safe but cannot say so. Legal under Swift 5,rejected by strict checking. Kept in their own commit so they are easy to see.
Where the escape hatches are
@unchecked Sendableandnonisolated(unsafe)each appear only where the typereally is thread-safe and cannot express it, and every one carries a comment
saying why.
nonisolated(unsafe)is used exactly once, for cancelling aTaskfrom a
deinit— documented safe from any thread.Reviewing
The migration commit is large but mechanical; the interesting commits are the
two concurrency fixes and the signing change. Builds clean with no warnings
introduced.
Follows on from this:
DhavalFatnani:split/2-ambient-recorder(36 commits)DhavalFatnani:split/3-dashboard-insights(4 commits)Both are pushed, build, and pass tests. I will open them once this lands, to
keep review load to one PR at a time.
